c# - Calling Windows Form Show() method using reflection crash -


i have following class (exposed com) using wrapper show forms called vb6.

public class netform : inetform {     public netform(assembly assembly, string name, object[] parameters)     {         assembly = assembly;         name = name;         createinstance(parameters);     }      private assembly assembly { get; set; }     private string name { get; set; }     private form instance { get; set; }      private void createinstance(object[] parameters)     {         type type = assembly.gettype(name);         type[] types = new type[parameters.length];         (int idx = 0; idx < parameters.length; idx++)             types[idx] = parameters[idx].gettype();          constructorinfo ci = type.getconstructor(types);         instance = (form)ci.invoke(parameters);     }     public void show()     {         instance.visible = true;         instance.show();       // crashing     }     public void showdialog()     {         instance.showdialog();  // works     } }  public class netassembly {     public netassembly(string fullname)     {         init(fullname);     }      private assembly assembly { get; set; }      private void init(string name)     {         assembly = assembly.loadfrom(name);                 }      public netform getform(string namespace, string name, object[] parameters)     {         name = string.concat(namespace, ".", name);         return new netform(assembly, name,parameters);     } }
  1. showdialog() works perfectly.
  2. show() not being displayed if visible property not set true. when setting true, form partially being displayed , crash after few seconds.

i using unittestproject check it:

[testclass] public class netformunittest {     [testmethod]     public void showtestmethod()     {         var assembly = new netassembly(assemblyfullname);         var form = assembly.getform(namespace, formname, new object[] { "item1" });         form.show();     } }

what correct way call show() method?

your form needs message pump (like application.run creates). reason showdialog creates own message loop.

so adding application.run(forminstance) should solve problem.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
